LSI 8751D - Manual (Page 41)

Operational Environment 3-3
The PCI PRSNT1/ and PRSNT2/ pins are set to indicate a 7.5 W
maximum configuration.
3.1.3 Thermal, Atmospheric Characteristics
The board operates in an environment defined by the following
parameters:
•
Temperature range: 5 to 55
°
C (dry bulb)
•
Relative humidity range: 5 to 90% noncondensing
•
Maximum dew point temperature: 32 ° C
3.1.4 Electromagnetic Compliance
The board minimizes electromagnetic emissions, susceptibility to radio
frequency energy, and the effects of electromagnetic discharge. The
board meets the requirements of FCC and CISPR Class B limits and is
marked with the FCC Class B ID: B8J8251AD.
3.1.5 Safety Characteristics
The bare board meets or exceeds the requirements of UL flammability
rating 94 V0. The bare board is also marked with the supplier’s name or
trademark, type, and UL flammability rating. Because this board is
installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit.
3.2 Operational Environment
The LSI8751D is designed for PCI computer systems with a standard
bracket. The SDMS software operates the board, but the design of the
board does not prevent the use of other software.
3.2.1 The PCI Interface
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through the edge connector J1, which provides connections on
both the top and bottom of the board. The signal definitions and pin
numbers conform to the PCI Local Bus Specification Revision 2.1
standard. The signal assignments are shown in
Table 1.2 and Table 1.3 .
